CASTING-TABLE.

Specification of Letters Patent.

Patented July, 25, 1911.

Application filed November 29, 1910. .Serial No. 594,800.

the United States of America, residing` at e Charleroi, in the county ofVvrashington and State of Pennsylvania, have invented certain new anduseful Improvements in Casting-Tables, of which the following is aspecification, reference being had therein to the accompanying drawing.

This inventionrelates to a casting table especially designed for themanufacture of sheet or plate window glass, and the primary object ofour invention is to provide a novel tiltable table upon which plateglass can be expeditiously and economically produced.

Another object. ofthe invention-is to obviatc the necessity ofmanufacturing large sheets or plates of glass by first producing acylinder',*capping and splitting the same.

A further object of the invention is to furnish a casting table withpositive and reliable means in `a manner as will be hereinafter setforth for equally distributing and pressing molten glass upon thecasting table,

whereby the sheet or plate of glass produced4 can be tilted forannealing` purposes with smooth and uninterrupted surfaces. i

A still fu er object of the invention is to provide a casting tableconsisting of comparatively few parts compactly assembled and easilymanufactured.

A still further object of the invention is to accomplish the aboveresults by a ma-A chine that is simple in construction, durable,inexpensive to manufacture and efficient for producing` sheets or platesof glass.

With the above and such other objects in view las may hereinafterappear, the invention consists -of the novel construction, combinationand arrangement of parts to be hereinafter specifically describedl andthen claimed.

Reference will now be had to the draw ings forming part of thisspecification, wherein like numerals of reference designatecorresponding parts, in which .Figure 1 is a side elevation of themachine, Fig. 2 is arear elevation of the same, Fig. 3 is a longitudinalsectional view of the table, Fig. 4 is a plan of the same, Fig. 5 is aperspective view of a detached guide, and Fig. 6 is a perspective viewof a detached starting or loosening device adapted to form part of thetable.

The reference numerals 1 denote base plates mounted upon a suitablefoundation and supporting standards 9. and 3 having the upper endsthereof provided with bearings 4 for a revoluble shaft 5. Revolublymounted upon the shaft 5 are a winding drum (3, ahois'ting drum 7 and adrum 8 to which is secured one end of a cable 9 which is wound upon the-drum 8` and. provided with a counter-balance weight 10.

11 denotes bearings carried `by the rear' sides of the standards 2 and 3for a revoluble shaft 12 ,having one end thereof provided with a crank13. Mounted 'upon the shaft 1'2 is a drum 14 to which is attached oneend of a cable 15, said cable being wound upon the drums 14 and 6 withthe other end "of the cable attached to the drum 6.

1G denotes a shaft journaled in the standards and 3 adjacent to thebearings 11 and mounted upon saidl shaft between'said bearings aresupports 17 for a presser block 18,-said supports being secured to theupper side of the block 18 by set screws 19 or other adjusting means.The' outer end of the block 18 is provided with an adjustable transverseknife 20 adjusted' through the medium of set screws 21. .Attached to theouter end of the `block 1S through the medium of an eye-bolt Q9. is oneend of a cable 23 having the opposite end'thereof wound upon and securedto the drum 7.

Z4 denotes oppositely disposed pedestals located adjacent to thestandards 2 and 3 and mounted upon the upper ends of said pedestals arebearings 25 in which is joury naled a shaft 26. Mounted upon the shaft2G between the pedestals 24 are the de' pivotally connected to saidbearing by a curved link 3Q is the outer end of a crank 33 mounted upona rock shaft 34 supported by the standards 2. and 3 contiguous to thelower ends thereof. -Mounted upon the end of the shaft34 adjacent to thestandard 2 is an singularly disposed arm and fixed upon the upper end ofsaid arm is a weight 38 adapted to facilitate the moving; and holding ofthe table either in a horizontal or tilted position.

37 denotes two angle guides pi-votally mounted by pins idupon the table28 at the rear end thereof and adjacent to the lon-gr tudinal edges ofsaid table, The lateral franges of the guides 37 are extended at theforward ends of lsaid guides, as at 39 -and provided with angularlydisposed slots d0, Extending upwardly through theV slots d() are thecrank pins il of a rock shaft li2 journaled in depending bearings 4:3,carried by 'the under side ofthe table adjacent to the forward endthereof. y @ne end of the rock shaft l2 has crank or suitable handle dtwhereby it can be easily rocked toshift the angle guides 87 upon thetable 28.

fit-5 denotes an angie bar arranged transversely of the table at therear'end thereof, said bar having the lateral flange 46 thereofslotted?, t? and prt vided with rearwardly extending apertnred lugs (t8.The angle bar d5 is retained upon the rear end of the table by guidepins orbolts i9 extending through the slots l? into the table 28. i?ivly mounted between. the apertured lugs ay a pin 50 is an arm 51fulcrunled7 as at between depending bearings 587 carried 1e rear end ofthe table. The lower end ythe arm 51 is pivotally connected, as at to arod 55 and said rod is pivotally cond, as at 58 to an or rating lever 5fy' 'mounted in a bearing 58 arranged a po nt in the of the standards 2and 3 and in alineinent with the longitudinal axis of the table. Theelements l5 to 58 inclusive constitute a starting or loosening devicethat. will be hereinafter referred to.

fA notes rails arranged between the s 2d and constituting i. ear ortruck 60 having a slab 6l adapted to receive a plate or sheet of glassfrom the table 28, the car or truck 60 being arranged wheini:'Yr it beeasily shifted into an annealing oven or furnace 62. Located at thesides of the track are' supports 63 for a transverse inclined chute 84,said chute having the lower edge thereof in proximity to the slab 6i ofthe car er truck 60 and the upper edge thereof positioned whereby' whenthe table 28 tilted, the surface of said table will be in a plane withthe surface of the chute 6d, thereby allowing the sheet or plate ofglass upon the table to slide by gravity over the chute on to the slabB1 with out becoming distorted or injured.

In operation, it is necessarythat the at? tendant of the machine shiftthe' angle guides inwardly, correctly position the transverse angle bar4:5, have the table 28 in horizontal position, the presser block 18 inan velevated position, and the car or truck 60 track: for a essere inposition with Ythe forward edge ofthe slab Gl.' adjacent to the loweredge of the chute Gil. rThe molten Lglass can then be poured upon thetable 28 and the shaft l2 rotated to lower the presser block 18 upon themolten glass, whereby it will be evenly distributed upon the table andpressed by the weight of the bloclr to that extent as to forni a sheetof tglass having a lower and upper smooth surface. "When the block 18 islowered7 the knife 2O thereof severs the forward edge of the plasticsheet or plate and limits the downward movement of the block 18,consequently by adjusting' .the knife 20 and the set screws 19, thethickness of the sheet or plate'of glass upon the table 28 can beregulated. The pressure of the block 18 upon the glass causes the glassto congeal and produce a plastic sheet or plate. The attendant of themachine then rocks the shaft 4t2 and through the medium of the crankpins il shifts the forward ends of the guide bars 37 outwardly, therebyreleasing"v the longitudinal edges of the plastic sheet or plate. Theattendant can then elevate the block 18 and tilt the table 28 and byoperatingl the lever 57, the transverse angle bar 49 will be shiftedsufficiently to loosen and start the plastic sheet or plate upon thetable 28, whereby it will slide over the chute 64 on to the slab 6i. ofthe car or truck 60, said car or truck being moved forward towardtheannealing oven as the plate or sheet passes on to thev slab (il.After the plastic sheet or plate of Xglass has left the table 28, saidtable can be restored to its normal position) for another' casting ofglass.

Frein the foregoing it will be observed that. We have devised a tiltablecasting table in connection with which certain devices are employed forinsuring a high degree of perfection7 besides expediting the product-ionof sheet or plates of glass, and while in the drawings there isillustrated a preferred embodiment of the invention, it is to beunderstood that the structural elementsthereof are susceptible to suchchanges as fall within the scope of the appended claims.
